Mark was in Berlin last week week for two days to support the need for a radical agreement at the UN conference on climate change in December. As the Prime Minister's special representative on global carbon trading, he has called in his recent report for a new international carbon trading system with tough caps on emissions as one of the ways of limiting the rise in the earth’s temperature as a result of climate change to 2° C.

He was the main speaker at a conference on Thursday with leading German politicians, Non-Governmental Organisations and industrialists.

Mark said: "We desperately need a tough agreement on climate change at Copenhagen. A reformed carbon trading system is only part of the solution but it could certainly make a real difference alongside other measures."

The visit was in support of the UK Government’s efforts to get international agreement in Copenhagen in December on ambitious, new targets for reducing emissions.
